--------------------------------

             Summary: Dynamic NM Resources Configuration file should be simplified.
                 Key: YARN-4160
                 URL: https://issues.apache.org/jira/browse/YARN-4160
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Junping Du
            Assignee: Junping Du


In YARN-313, we provide CLI to refresh NMs' resources dynamically. The format of dynamic-resources.xml is something like following:
{noformat}
<configuration>
  <property>
    <name>yarn.resource.dynamic.node_id_1.vcores</name>
    <value>16</value>
  </property>
  <property>
    <name>yarn.resource.dynamic.node_id_1.memory</name>
    <value>1024</value>
  </property>
</configuration>
{noformat}
This looks too redundant from review comments of YARN-313. We should have a better, concisely format.
